Weighted Scope Probe Parking Stand
A 96 x 62 x 34 mm ballast stand that parks three oscilloscope or multimeter probes tip-down in tapered sockets that grip any 6.4–13 mm probe barrel, so a tugged lead can't drag the holder off the bench. The open rear well takes ~34 cm3 of steel nuts, shot or sand (≈130–250 g), a keyhole comb snaps 4–5.5 mm probe leads for strain relief, a 64 x 7 mm dish holds hook and spring tips, and two 3.4 mm M3 clearance holes let you bolt it to the bench.
